In this paper we describe a new method for the synthesis of camalexin (1) based on the reaction of 1-(tert-butoxycarbonyl)indole-3-carboxaldehyde with methyl Lcysteinate hydrochloride, followed by oxidation and decarboxylation. Compounds 1, and inter...
New podand and crown ether derivatives of 3,5-disubstituted 4H-pyran-4-one (8-11) were prepared by the nucleophilic substitution reaction of 3,5-bis(bromomethyl)-2,6-diphenyl-4H-pyran-4-one with o-nitrophenol, 8-hydroxyquinoline, 2-hydroxymethyl pyri...
Eight new furan derivatives have been prepared and characterized. These compounds were obtained by condensation of aminosugar and aminocyclitol intermediates with furan derivatives.
The genesis of the purple dye from shellfish, its composition, origin, intermediates, analysis and synthesis of the components, 6,6’-dibromoindigo, 6-bromoindigo and 6,6’-dibromoindirubin are reviewed.
Epoxide ring opening is a frequently required transformation in Organic Synthesis. In this paper we describe the application of NbCl5 for this purpose using three different substrates. Chlorohydrins, 1,2-diols, products containing solvent residues as...
The single crystal structure of cis-dichlorobis(triphenyphosphite) platinum(II), [PtCl2(P(OPh)3)2] has been determined. This complex crystallises in the orthorhombic space group, P212121 with cell constant, a=10.4135(13), b=14.0635(16), c=23.505(3) Ǻ...
The synthesis of a series of new n-propyl and n-butyl chain containing 1-arylpiperazine derivatives of quinazolidin-4(3H)-one (7) 2-phenyl-2,3-dihydrophthalazine-1,4-dione (8) and 1-phenyl-1,2-dihydropyridazine-3,6-dione (9) as potential serotonin re...
